I would like to share with you fantastic experince of using Terminal services gateway – a new feature of Windows server 2008 terminal services.
It does allow user to use gateway that listens on port 443 (HTTPS / SSL) and then “route” remote desktop protocol to workstations inside network and FOR ME GREAT FEATURE even on other servers on the internet (so now you can lock RDP client to your IP address (where you have your TS Gateway server) and you will be able to access your servers through your TS Gateway and in this way even more secure your remote access).

I hope you will enjoy this fantastic feature!

To understand better I have some pictures to show…
